Ubisoft will bring the Vita version of Rayman Legends up to par with the console versions with a free DLC update containing the missing levels.
Outrage was sparked when it emerged that Rayman Legends on Vita was missing the 28 'Invasion' levels, despite an earlier statement from Ubisoft which claimed the portable version "includes all of the original Rayman Legends content, as well as five exclusive maps".
But Ubisoft communications manager Gary Steinman has said the publisher will later add the missing content for free.
"Due to a longer development time than expected, we couldn't initially include the Invasion Mode - essentially, a second take on existing Rayman Legends maps -- in the Vita version of the game," he explained.
"However, we can confirm that the Invasion Mode will be added via a free patch, at a later date," said Steinman.
In late August the Vita version was delayed for a further two weeks in the UK, "in order to apply the final level of polish gamers expect from a Rayman game".
In our Rayman Legends review, we said the game is "an absolute joy to play", offering "essential platforming shenanigans" that are "best experienced on Wii U".
